Siemens SINAMICS S120 Equipment Manual page 73

If the terminals are not reconnected to the actual line voltage:
• The required cooling capacity cannot be provided because the fan rotates too slowly;
• The fan fuses may blow due to an overcurrent.
Note
With the fan transformer (500 to 690 V 2 AC), a jumper is inserted between terminal "600 V"
and terminal "CON" ((1) in the picture above). Terminal "CON" is for internal use.
The order numbers for fan fuses that have blown can be found in the spare parts list.
